The amount of money a country has to its name was one of the key factors taken into account to measure prosperity, but the Legatum Institute took other issues into account, too, one being safety and security.

The index looked at data relating to 149 countries and produced a thorough ranking, based on the national security of the listed countries and the personal safety of people living there.

13. United Kingdom — Theresa May's UK has improved its ranking by 10 places compared to the Legatum Institute's last index.

12. Netherlands — Located in the northwest reaches of Europe, the Netherlands just misses out on the world's top 10 safest countries.

11. Hong Kong — The United Nations doesn't recognise Hong Kong as an independent state but it is still one of the safest places in the world. It was ranked the safest place in the world last year, though.
